<h2>
Compiling for Macintosh OS X</h2>

<blockquote>To compile a Macintosh OS X CoreAudio application with the
PortAudio library you will use the following source files:
<blockquote>pa_mac_core/pa_mac_core.c<br>
pa_common/pa_lib.c<br>
pa_common/portaudio.h<br>
pa_common/pa_host.h<br>
pa_common/pa_convert.c<br>
pablio/ringbuffer.c<br>
pablio/ringbuffer.h</blockquote>
</blockquote>

<h3>
Using Apple Project Builder</h3>

<blockquote>Create a new ProjectBuilder project. You can use a "Tool" project
to run the PortAudio examples.
<p>Add the source files from above to your Project.
<p>Add both the Apple CoreAudio.framework and the AudioToolbox.framework
to your project by selecting "Add FrameWorks..." from the Project menu.
<p>Compile and run the "pa_tests:patest_saw.c" file first because it is
the simplest.</blockquote>

<h3>
Or Using Metrowerks CodeWarrior 8</h3>

<blockquote>by James Vanlommel</blockquote>

<blockquote>Create a new CodeWarrior project using Mac OS C++ Stationery.
<br>Then choose Mac OS X Mach-O > Standard Console > C++ Console Mach-O.
<p>In the project window, Clear the HelloWorld.cpp file and add the source
files from above to your Project.
<p>Add a test file of your choosing, like
<br>&nbsp;&nbsp; patests&nbsp;&nbsp;&nbsp; /patest_sine8.c
<br>&nbsp;
<br>Add the frameworks to the Frameworks tab using Project > Add Files...
<br>&nbsp;&nbsp; CoreAudio
<br>&nbsp;&nbsp; AudioToolbox
<p>(The System framework should already be a part of the project.)
<p>Open the current target's settings, and in Language Settings > C/C++
Language, uncheck (disable) the "ANSI Strict" setting. (Do this for both
Debug and Release projects, if necessary.)
<p>Edit pa_mac_core.c:
<br>&nbsp;&nbsp; On line 1546, cast the PaHost_AllocateFastMemory() result
to a (char *) or you will get a compile error.
<br>&nbsp;
<br>Compile and run. (may need to run from a terminal window)
<p>I've successfully built patest_sine8.c this way using the CVS .tar version
of portaudio (date: 2003-04-27). I get 17 warnings during compilation,
all of which deal with unused variables or arguments.</blockquote>
